The HCF and the LCM of two numbers are 5 and 175, respectively. If the ratio of the two numbers is 5 : 7, the larger of the two numbers is _______.

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 35​​​​​​.

We know that,

⇒ a × b = L.C.M × H.C.F

The ratio of the two numbers is 5 : 7 = 5x : 7x

⇒ 5x × 7x = 5 × 175

⇒ 35x2 = 5 × 175

⇒ x2 = 25

⇒ x = 5

One number = 5x = 25

Another number = 7x = 35

Largest number = 35
